Bent Cable Bracket Structure for High-Reaction Wiring Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiring members struggle to maintain a reliable bent state under large reaction forces, particularly when the diameter or number of wires increases, leading to instability and potential damage.
Innovation Solution
A wiring member design featuring a bracket with inner and outer wall portions that hold the wire in a bent shape, combined with a resin molded portion for additional support and protection, which suppresses friction and exposure, and includes a vehicle fixing portion to secure the wire effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the diameter or number of wires increases, then the reaction force acting to return wires to initial state increases, but the ability to hold the bent state reliably deteriorates
Solution Approach 1:
The bracket divides the support function into multiple segments: the holding portion segments the wire support into inner and outer wall portions, while the bend holding portion further segments the support at the bent portion location. This segmentation allows distributed support against the increased reaction force from larger diameter or multiple wires.
Solution Approach 2:
The invention adds a dimensional element by extending the vehicle fixing portion outward from the holding portion. This creates an additional attachment point dimension that enhances the overall stability and reliability of holding the bent state, providing support in multiple spatial dimensions rather than just at the bend location.
2Device complexity
If a single holding portion is used, then the structure is simple, but the reliability to hold the bent state under large reaction forces deteriorates
Solution Approach 1:
The holding portion is segmented into an inner wall portion and an outer wall portion, creating multiple support points within a single component. This segmentation provides enhanced reliability for holding the bent state without requiring multiple separate brackets or complex assembly structures.
Solution Approach 2:
The bracket serves multiple functions within a single component: it holds the wire in position, maintains the bent state through the bend holding portion, and provides structural support through the vehicle fixing portion. This multi-functionality achieves high reliability without increasing device complexity through additional separate components.
3Reliability
If the wire is tightly constrained to maintain bent shape, then the bent state is held reliably, but friction and exposure risks increase
Solution Approach 1:
The bracket applies localized support quality at specific locations: the holding portion provides support at the wire body location, while the bend holding portion provides targeted support at the bent portion. This local quality approach maintains the bent state reliably without requiring tight constraint along the entire wire length, thereby reducing friction and exposure risks in non-critical areas.

AI summary
Provided is a wiring member that can be held in a bent state more reliably even if a reaction force is large. A wiring member includes a cable including a bent portion that is routed along a bent path, and a bracket including a holding portion for holding the cable and a vehicle fixing portion that protrudes outward of the holding portion, and the holding portion includes a bend holding portion for holding the bent portion of the cable, and the bend holding portion includes an inner wall portion located on an inner circumferential side of the cable, and an outer wall portion located on an outer circumferential side of the cable.
